HARROW.

SPECIFICATION forming part of Letters Patent No. 662,605, dated November 27, 19010.

Application filed January 31, 1900. Serial No. 3,495. (No modelfl To aZZ whom it may concern: y

Beit known that I, WALTER P. SMITH, a citizen of the United States, residing at Clarksville, in the county of Butler and State of Iowa, have invented a new and useful Harrow, of

which the following is a specification.

This invention relates to harrows, and has for one object to improve the construction shown in my prior patent, No. 638,769, dated December l2, 1899, and also to provide an improved sectional device which may be conveniently folded, so that the machine may pass through a gateway and also may be raised from the ground when passing over roads and in other conditions when not required for use. It is also designed to provide for the maximum vertical play of the harrowsections, so as to accommodate the latter to very uneven ground, andat the same time to preserve the strength and durability of the barrow.

A further object resides in providing improved means for elevating the central section and folding the end sections and to locate such means within convenient reach of the driver-s seat, so that the operator may have the entire machine under complete control without leaving his seat, and, finally, it is designed to provide an improved draw-bar which is connected to each section, so as to insure an even draft, and is also arranged to fold with the end sections without interfering with the draft upon the entire harrow. p

With these and other objects in view the present inven tionconsists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being u nder` stood that changes in the form, proportion, size, and minor details may be made within the scope of the cla ms without departing from the spirit or sacrificing any of the advantages ofthe invention.

ln the drawings, Figure l is a perspective View looking at the rear of the improved harrow and showing one of the end sections in its elevated and folded position. Fig. 2 is a plan view showing allof the sections in position for use. Fig. 3 is a central sectional view from front to rear of the harrow and illustrating the means for elevating the central section. Fig. 4 is a similar view illustrating the elevated position of the central section and also the elevated and folded position of one'of the `end sections. Fig. 5 is a detail plan view of one end of the draw-bar and illustrating the foldable construction thereof.

Fig. 6 is a detail perspective View showing the folded position of one end of the draw-bar. Fig. 7 is a detail View of the means for adjusting the brace for the central barrow-section.

Corresponding parts in the several figures of the drawings are designated by like characters of reference.

Referring tothe accompanyingdrawings, it will be seen that the present harrow comprises three transverselyalined barrow-sections, of which the central section is designated by the letter A and the opposite end sections by the characters B and B, respec tively. Each of these sections is constructed substantially' as set forth in my prior patent, although they may be of any preferred form. As shown in the drawings, each section comprises a plurality of toothed beams l, which are loosely suspended from the opposite crossbars 2. ln order that the teeth may beinclined at different angles by an oscillation of the beams, the latter are connected to an intermediate transverse rod 3, which is pivotally connected to each beam by means of a separate link 4, and' this bar is held in its adjusted position by means of a pivotallymounted hooked brace 5, which is carried by the rear beam and is designed to engage one of a series of perforations 6, formed in the rod 3. However, any other preferred means for adjusting the rod may be employed.

The central barrow-section A is supported upon the arched and wheeled axle 7, which is provided with the usual tongue 8, and the IOO tal arm 17, as may be preferred.

rest 12, which has its opposite ends supported upon thek axle and at opposite sides `of the tongue.

To elevate the central section, there are provided the opposite ropes 13, which are connected to thecentral beam of the section and extend upwardly and through the respective pulleys 14, which are mounted in the opposite ends of the arched foot-rest 12. Mounted transversely upon the tongue 8, located in advance of the foot-rest 12, and extending equally at opposite sides of the tongue is a rock-shaft 15, which is provided at each end with the angularly-related arms 16 and 17, respectively, which are locatedupon the forward side of the shaft and are disposed at snbstan tially right angles to each other. The members of each pair of arms are located close together, as best illustrated in Fig. 2 of the drawings, and the arm 16 is in the form of a bell-crank, so as to be disposed at the forward side of the rock-shaft and at the same time not to interfere with the operation of the arm 17. However, the normally pendent arm 16 may form aV part of the normally horizon- A The forward end of each rope 13 is connected to the lower extremity of the adjacent arm 16, so that when the shaft 15 is rocked to throw the arm upwardly and forwardly the rope will be drawn upwardly through the pulley 14, and thereby elevate the central barrow-section. The forward end of each arm 17 is connected u to the front beam of the central section by means of a chain or rope 18, so as to assist in the elevation of the section and to preserve the substantially horizontal position thereof.

In order that the shaft 15 may be conveniently rocked, there is provided a ratchet-lever 19, which is mounted upon the shaft at a point adjacent to one side of the tongue and designed for engagement with a ratchetwheel 20, carried by the shaft. By this arrangement the operating-lever 19 is located in convenient reach from the drivers seat, so that the central section maybe readily controlled by the operator. A suitable gravity pawl or detent 21 is mounted upon one side of the tongue and located intermediate of the rock-shaft andv the foot-rest 12, so as to engage the ratchet-Wheel 2O and also to be in convenient position to be raised by the foot of the driver when it is desired to free the rock-shaft.

When the central harrow-section is in its operative position, the ropes or flexible suspending connections 13 are slack, so as to provide for the maximum Vertical play of the section, and thereby accommodate the latter to very uneven ground.

The outer It will thus be ap-v end of each brace is provided with a ring or link 23, which loosely embraces an arched and vertically-disposed guide-rod 24, which is secured to the adjacent upright portion of the axle, and the opposite end of the brace is connected to a plate 25, which is secured to the intermediate beam of the central section and is provided with a plurality of perforations for adjustable engagement with a suitable fastening-bolt, so that the brace 22 may be conveniently tightened, as best illustrated in Fig. 7 of the drawings. By this arrangement the central section is prevented from swinging into engagement with the wheels, and the outer ends of the braces 22 are designed to slide vertically upon the guide-rods 24, so as to accommodate the braces to the movement of the section and also to the vertical adjustment thereof.

By reference to Figs. 3 and 4 of the drawings it will be seen that theadjusting-bar 3 of the central section is provided with an intermediate downwardly bowed Yportion 26, which is designed to form a notch for the reception of the axle in the elevated position of the section, so that the latter may have the maximum degree of adjustment.

The means for folding each end section comprises an upright standard 27, located between the wheels and rising from the adjacent upright portion of the axle. A shorter and supplemental standard 28 rises from the outer end of the axle, exterior of the wheel, and is connected to the main standard by means of Va suitable brace 29, located above the wheel. Pivoted at a point intermediate of the ends of the outer standard 28 is an arm 30, which comprises opposite parallel members that embrace the standard and are connected at their outer ends by means of a yoke-shaped sti'rrup 31, which is designed to embrace the standard in the elevated position of the arm. -This arm is operated by means of a rope or other flexible connection 32, which extends upwardly from the outer end of the arm and passes loosely through an opening in the standard, so as to be in position for convenient operation from the drivers seat. To hold the arm in its elevated position, a suit-able cleat 33 is provided upon the rear'side of the main standard 27 and with which cleat the rope 32 is designed to be engaged.

Fixed to thevouter end of the axle and exteriorly of the wheel is a cross-bar 34, which extends ina direction Vfront and Vrear of the harrow. At each end of this cross-bar there is provided a substantially U -shaped bracket 35, which extends laterally outward from the cross-bar, and the shank of the bracket is provided with a vertically-disposed opening 36, which is disposed between the inner end of the bracket and the outer side of the crossbar. Extending looselj1 th rough each of these guide-openings is a chain or other flexible connection 37, which has its lower end con- IOO IIO

hected to the inner end of one of the beams of the adjacent end section and the upper end being connected to a rod 38, which has its upper end connected to the outer end of the arm 30. Extending from the upper end of the main standard 27 and downwardly to the adjacent outer section is a suitable block and tackle 39 for raising the outer end of the section when the latter is to be folded.

From the foregoing description it will be apparent that each outer section is held in place by means of its respective block and tackle and chains 37, while at the same time the section is free to move vertically, so as to accommodate itself to uneven ground. However, there is no connection whatsoever between the barrow-sections, so that each of the latter is independent of the other, and therefore may be adjusted individually. As there is no connection between the contiguous ends of the adjacent sections, there is no danger of the latter binding upon each other during the adjusting operation.

When it is desired to elevate and fold one of the end sections, as shown in Figs. l and 4 of the drawings, the flexible connection 32 is operated to swing the arm 30 upwardly, and thereby raise the inner end of the section, after which the block and tackle is operated to swing upwardly and inwardly the outer end of the section, whereby the latter is both elevated and folded inwardly. In the folded position of the section, as best shown in Fig.

'1 of the drawings, the beams to which the chains 37 are connected are` received within the respective brackets 35, so as .to effectually brace the section against accidental movement in a direction front and rear of the device. When folded, the intermediate beam of the section is designed to rest against the block or head 40, which is provided upon the upper end of the outer standard 28, so as to form an additional brace for the section.

The doubletree 4l is mounted beneath the tongue or pole 8 and is supported by means of a suitable bracket 42, which is pendent from the under side of the tongue, so as to place the draft as low as possible, and thereby relieve strain from the draft-animals. Located in rear of the doubletree and also below the latter is the main draw-bar 43, which is connected to the central section by means of suitable hooks or links44 and to the tongue or pole by means of the draft-rods 45.

At each end of the draw-bar there is provided a supplemental foldable bar 46, the inner end of which is received within a notch 47, formed in the rear side of the main drawbar. The inner end of the foldable bar is provided with a metallic cap 48,which has a perforate ear 49 foll engagement with a transverse pivot-bolt 50, which extends through the main draw-bar. Secured to the front side of the outer end'of the foldable bar is an inclined brace-rod 5l, which extends inwardly across the front face of the main draw-bar and is pivotally connected to the forward end of the bolt 50. Extending between the brace 5l and the foldable bar is a transverse brace 52, which forms a shoulder for engagement with the adjacent outer end of the draw-bar. At the outer end of the draw-bar is a metal strap 53, which extends rearwardlyacross the lower side of the notched portion of the drawbar, so as To form a seat,which normally supports the foldable bar in its operative position, and the rear end of this seat is provided with an upwardly-directed shoulder 54 for engagement with the rear side of the foldable bar, so as to hold the latter in place. This strap 53 also extends in advance of the front edge of the draw-bar and is provided with an upstanding lug or shoulder 55 to receive the brace-rod 5l between the draw-bar and the shoulder when the foldable bar is in its normal or extended position. The foldable bar is connected to the adjacent outer harrowsection by means of the links or hooksI 56, so

' as to have a flexible connection with the section. When either of the outer sections is folded, the adjacent foldable bar 46 will also fold upwardly upon its pivotal connection with the main draw-bar and without interfering with the draft upon the main draw-bar.

In order that the foldable bars may not be accidentally moved upwardly by the movement of the harrow, I have provided each bar with a lock in the form of a bell-crank latch 57, which is pivoted to the upper side of the main draw-bar intermediate of the outer end of the latter and the pivotal connection of the foldable bar and designed to work transversely of the latter. The rear end ot' the latch overhangs the front edge of the foldable l bar and is provided with an upstanding and forwardly beveled or inclined catch-head 58. At the forward end of the latch there is provided a coiled spring 59, having one end connected to the adjacent end of the latch and its opposite end connected to the main drawbar, so that the catch end of the latch is normally held across and in engagement with the upper side of the foldable har, whereby the latter is prevented from being accidentally turned upwardly by the movement of the harrow. To release the latch when it is desired to fold either end section, there is provided a rope or other flexible connection 60, which has one end connected to the forward end of the bell-crank latch, and the opposite end IOO IIO

thereof is located in convenient reach of the driver, so that he may pull the rope to release the latch from engagement with the foldable bar, whereby the latter is free to be folded. When the section is again extended to its wheeled support, and a vertically-movable barrow-section, of a rock-shaft mounted upon the support, arms carried by the rock-shaft, radiating therefrom, and arranged in different planes, which are angularly disposed one with the other, flexible suspending connections between the respective arms and the barrow-section, and means for operating the rock-shaft.
